Technology Description

Ion-exchange resin wafer electrodeionization (RW-EDI) is an energy-efficient, low-cost separation technology that directly utilizes electricity to remove ions from aqueous streams. It integrates commercially available components of ion-exchange resin material, membranes, and electrically driven separation devices to increase the energy efficiency and reduce the cost of processing aqueous streams. The technology offers enhanced fluid and flow distribution; higher conductivity; superior pH control; ease of materials handling and system assembly; and a porous solid support for incorporation of catalysts; biocatalysts; and other adjuvants. RW-EDI is a near commercial technology that won 2001 and 2006 R&D 100 Awards for chemicals/water purification and bio-based chemical/biofuel production.
